Description

Technical Field

[0001] The present invention provides a power supply, and more particularly, relates to a power supply assembly structure, which realizes electrical connection between an LED indicator light and a fan through a flexible circuit board, so as to simplify the assembly structure, improve space utilization, and realize automatic assembly of a main circuit board. Background Art

[0002] In recent years, with the rapid development of the electronics industry, power supplies have become increasingly important as an indispensable power supply device, so improvements to their structure and process have become more valuable. Today, in the manufacturing process of power supplies, most of them are still assembled manually. However, as the number of components in the power supply increases, the assembly of each component must be manually calibrated and fixed, which requires a lot of manpower.

[0003] For some electrical devices attached to the end of the shell in the power supply assembly structure, such as LED indicators or fans, it is necessary to connect them to the power supply unit of the internal main circuit board through flying wires. However, when the current power supply structure uses flying wires to electrically connect the LED indicator or fan to the supply unit on the main circuit board, the wires must be manually arranged above the main circuit board and then inserted into the connection terminals. The flying wires must avoid the parts on the main circuit board, and after assembly, the wires may also be lifted up, affecting the height limit. In addition to occupying the device space above the main circuit board, it cannot be completed through automated assembly.

[0004] In view of this, how to provide a power supply assembly structure, provide LED indicator lights and fan electrical connections to simplify the assembly structure, improve space utilization, and realize automatic assembly of the main circuit board, and improve the deficiencies of the prior art, is an urgent problem that needs to be solved. Summary of the invention

[0005] The purpose of this case is to provide a power supply assembly structure, which realizes the electrical connection of LED indicator lights and fans through a flexible circuit board, so as to simplify the assembly structure, improve space utilization, and realize the automated assembly of the main circuit board.

[0006] Another object of the present invention is to provide a power supply assembly structure. The flexible circuit board for realizing the LED indicator light and the fan power supply connection is arranged below the main circuit board, and does not occupy the parts space on the main circuit board. In addition, due to the thin thickness of the flexible circuit board, it does not occupy the parts space below the main circuit board. When the flexible circuit board is fixed to the bearing surface of the shell, the assembly process can be simplified by the design of the positioning seat, the positioning column and the positioning hole. On the other hand, the elastic conductive part of the flexible circuit board can be supported by the boss of the stamped shell or the additional reinforcement plate, and the height of the protrusion passing through the opening of the insulating part can be adjusted, thereby increasing the reliability of the assembly structure.

[0007] Another object of the present invention is to provide a power supply assembly structure. When the LED indicator and the fan are designed on the rear side of the housing, their power supply requirements can be achieved through a flexible circuit board, and the housing and the insulating member are assembled and clamped. The elastic conductive member of the flexible circuit board can be exposed through the opening of the insulating member to a protrusion height. When the main circuit board of the circuit board assembly is assembled to the insulating member and the housing, the installation gap is less than the protrusion height, and the conductive pad on the bottom of the main circuit board can be close to the opening and pressed against the elastic conductive member to form an electrical connection, thereby simplifying the assembly process and allowing the assembly of the main circuit board to be completed through automated assembly. On the other hand, when the circuit board assembly is installed on the housing and the insulating member, the input socket, the primary side circuit, the secondary side circuit and the output gold finger on the circuit board assembly are arranged from the rear side of the housing to the front side of the housing. The power supply requirements of the electrical devices on the rear side can be conducted through the flexible circuit board between the insulating member and the housing, and then electrically connected to the synchronous rectifier (SR) circuit board on the secondary side circuit through the conductive pad on the bottom of the main circuit board. The flexible circuit board is sandwiched between the housing and the insulating member, and a sufficient distance can be maintained between the primary circuit and the secondary circuit. In other words, the design of the LED indicator and the fan on the rear end of the housing being electrically connected to the conductive pad below the main circuit board through the flexible circuit board helps to simplify the assembly structure of the housing, the flexible circuit board, the insulating member and the circuit board assembly. The flexible circuit board can be pre-fixed to the housing, eliminating the use of flying wires and being free from wire restrictions, which can improve space utilization and help to realize the automatic assembly of the main circuit board.

[0076] refer to Figures 1 to 7, which discloses the power supply assembly structure of the first embodiment of the present case. In this embodiment, the power supply assembly structure 1 includes a housing 10, a flexible circuit board 20, an insulating member 30 and a circuit board assembly 4. It should be noted that the housing 10 and the insulating member 30 are both two-piece disassembled and assembled structures. In order to illustrate the assembly relationship between the housing 10, the flexible circuit board (FPC) 20, the insulating member 30 and the circuit board assembly 4, the housing 10 and the insulating member 30 refer to the parts that assemble and carry the circuit board assembly 4, and the other parts assembled later are marked with the upper cover assembly 50, which does not limit the combination type of the housing 10 and the insulating member 30 of this case, and is first described here. In this embodiment, the housing 10 includes a first end side 11 and a second end side 12 opposite to each other, a bearing surface 13 and a positioning seat 14. The first end side 11 and the second end side 12 are, for example, opposite rear end sides and front end sides along the first direction (X-axis direction). The positioning seat 14 is arranged on the bearing surface 13 and is located between the first end side 11 and the second end side 12. The flexible circuit board 20 is disposed on the bearing surface 13 of the housing 10, for example, from top to bottom along the second direction (opposite to the Z-axis direction). The second direction is perpendicular to the first direction. In the present embodiment, the flexible circuit board 20 is in the shape of an elongated strip, and when assembled to the bearing surface 13, it extends from the first end side 11 of the housing 10 along the first direction (X-axis direction) to the positioning seat 14. The flexible circuit board 20 includes an LED indicator 23 and an elastic conductive member 24, which are respectively disposed at the rear end 21 and the front end 22 opposite to each other. In the present embodiment, the LED indicator 23 of the flexible circuit board 20 is further disposed adjacent to the first end side 11 of the housing 10 to display the use status of the power supply. The elastic conductive member 24 at the front end 22 is electrically connected to the LED indicator 23 at the rear end 21. In other embodiments, a plurality of elastic conductive members 24 may be arranged, for example, along the Y-axis direction to assemble and connect the required power supply to the LED indicator 23 or other additional devices at the rear end 21, but the present case is not limited thereto. In this embodiment, when the flexible circuit board 20 is assembled to the bearing surface 13 of the housing 10, the elastic conductive member 24 is correspondingly assembled on the positioning seat 14 of the housing 10. In this embodiment, the insulating member 30 includes a rear end 31 and a front end 32 corresponding to the first end side 11 and the second end side 12 of the housing 10, and includes a through opening 33 that passes through the top and bottom surfaces thereof. The through opening 33 is spatially relative to the elastic conductive member 24 of the flexible circuit board 20 and the positioning seat 14 of the housing 10. When the insulating member 30 is assembled to the bearing surface 13 of the housing 10 from top to bottom along the second direction (opposite to the Z-axis direction), the flexible circuit board 20 is sandwiched between the bearing surface 13 of the housing 10 and the bottom surface of the insulating member 30. In addition, the elastic conductive member 24 on the flexible circuit board 20 is exposed through the through opening 33 of the insulating member 30. In this embodiment, the circuit board assembly 4 at least includes a main circuit board 40 , and a rear end 41 and a front end 42 of the main circuit board 40 correspond to the first end side 11 and the second end side 12 of the housing 10 , respectively.The main circuit board 40 has a conductive pad 43 disposed on the bottom surface, and the conductive pad 43 is spatially opposite to the through-hole 33 of the insulating member 30 and the elastic conductive member 24 of the flexible circuit board 20. When the circuit board assembly 4 is assembled to the insulating member 30 along the second direction (opposite to the Z-axis direction), the conductive pad 43 on the bottom surface of the main circuit board 40 is close to the through-hole 33 of the insulating member 30, and the conductive pad 43 of the main circuit board 40 and the elastic conductive member 24 of the flexible circuit board 20 are in contact with each other (e.g., Figure 6B As shown), the LED indicator light 23 and the main circuit board 40 are electrically connected, thereby simplifying the assembly process and allowing the assembly of the main circuit board 40 to be completed through automated assembly.

[0077] In this embodiment, the flexible circuit board 20 further includes a connector 26, which is disposed adjacent to the first end side 11 of the housing 10 and is electrically connected to the elastic conductive member 24. The power supply assembly structure 1 further includes a fan 60, which is disposed adjacent to the first end side 11 of the housing 10 and is electrically connected to the connector 26 via a connecting plug 61. Since the LED indicator 23 and the fan 60 are both disposed adjacent to the first end side 11 (rear end side) of the housing 10 and are electrically connected to the elastic conductive member 24 of the flexible circuit board 20, their power supply requirements can be met through the long strip of flexible circuit board 20. Figures 3 to 5 As shown, the housing 10, the flexible circuit board 20, the insulating member 30 and the circuit board assembly 4 can be assembled in sequence along the second direction (opposite to the Z-axis direction). Among them, the flexible circuit board 20 can be clamped between the housing 10 and the insulating member 30 by the assembly, and can also be pre-attached or fixed to the housing 10 or the insulating member 30 for assembly. After the housing 10, the flexible circuit board 20, the insulating member 30 and the circuit board assembly 4 are assembled, they can be fixed by screws or other fasteners or other means, and the present case is not limited thereto. Since the power supply connection of the LED indicator 23 and the fan 60 is realized through the flexible circuit board 20 configured under the main circuit board 40, the part space on the main circuit board 40 is not occupied. In addition, due to the thin thickness of the flexible circuit board 20, the part space under the main circuit board 40 is not occupied. In addition, the setting of the flexible circuit board 20 eliminates the use of flying wires and is not restricted by wires, which can improve space utilization and help to realize the automatic assembly of the main circuit board 40.

[0078] In the present embodiment, in the power supply assembly structure 1, the circuit board assembly 4 includes a primary circuit 44 and a secondary circuit 45 for ACDC power conversion. After assembly, the primary circuit 44 and the secondary circuit 45 are spatially opposite to the first end side 11 of the housing 10 and the second end side 12 of the housing 10, respectively. In the present embodiment, the power supply assembly structure 1 also includes an input socket 51 connected to the rear end 41 of the main circuit board 40 and adjacent to the first end side 11 of the housing 10 to assemble the input power. The main circuit board 40 also includes a gold finger 46 spatially opposite to the second end side 12 of the housing 10. In the present embodiment, the input socket 51, the primary circuit 44, the secondary circuit 45 and the gold finger 46 are arranged on the main circuit board 40, arranged along the first direction (X-axis direction), the primary circuit 44 is located between the input socket 51 and the secondary circuit 45, and the secondary circuit 45 is located between the primary circuit 44 and the gold finger 46. On the other hand, the circuit board assembly 4 also includes a synchronous rectifier (SR) circuit board 47, which is inserted on the main circuit board 40, corresponds to the conductive pad 43 in space, and is located in the area where the secondary circuit 45 is located. Since the primary circuit 44 and the secondary circuit 45 need to maintain a sufficient distance, when the DC power supply needs to be connected from the secondary circuit 45 to the LED indicator 23 and the fan 60 at the first end side 11 (rear end side), it must cross the primary circuit 44. The electrical connection is achieved through the flexible circuit board 20, which can avoid the space waste caused by the use of flying wires and solve the problem of wire management, improve space utilization, and help to realize the automatic assembly of the main circuit board 40.

[0079] In this embodiment, the positioning seat 14 of the housing 10 includes a boss 16, which protrudes upward from the bearing surface 13 and is assembled with the elastic conductive member 24 that supports the flexible circuit board 20 after assembly. In this embodiment, the positioning seat 14 includes at least one positioning post 15, and the flexible circuit board 20 includes at least one first positioning hole 25, which is spatially opposite to the at least one positioning post 15. When the flexible circuit board 20 is assembled with the housing 10 (such as Figure 3 ), at least one positioning post 15 passes through at least one first positioning hole 25, so that the flexible circuit board 20 is assembled to the bearing surface 13 of the housing 10 along the second direction (opposite to the Z-axis direction), and the elastic conductive member 24 is located on the boss 16 of the positioning seat 14. In addition, the insulating member 30 also includes at least one auxiliary positioning hole 34, which is spatially opposite to the at least one positioning post 15 and is adjacent to the through hole 33. When the insulating member 30 is assembled to the flexible circuit board 20 and the housing 10 (such as Figure 4), at least one positioning post 15 also passes through at least one auxiliary positioning hole 34, so as to facilitate the alignment of the through opening 33 of the insulating member 30 and the elastic conductive member 24 of the flexible circuit board 20. In other words, when the flexible circuit board 20 or the insulating member 30 is fixed to the bearing surface 13 of the housing 10, the assembly process can be simplified by the design of the positioning seat 14, the positioning post 15, the first positioning hole 25 and the auxiliary positioning hole 34. Of course, the present invention is not limited to this.

[0080] In this embodiment, after the housing 10, the flexible circuit board 20 and the insulating member 30 are assembled, the elastic conductive member 24 of the flexible circuit board 20 and the top surface of the insulating member 30 form a protrusion height H (eg Fig. 6A In addition, after the main circuit board 40 is further assembled onto the insulating member 30, a mounting gap G is formed between the conductive pad 43 of the main circuit board 40 and the top surface of the insulating member 30 (as shown in FIG. Figure 6B As shown). Since the installation gap G is smaller than the protrusion height H, when the main circuit board 40 of the circuit board assembly 4 is assembled to the insulating member 30 and the housing 10, the conductive pad 43 on the bottom surface of the main circuit board 40 can be close to the through-port 33 and pressed against the elastic conductive member 24 to form an electrical connection, thereby simplifying the assembly process and allowing the assembly of the main circuit board 40 to be completed through automated assembly. Of course, the type of conductive pad 43 pressed against the elastic conductive member 24 in this case can be adjusted according to actual application requirements. On the other hand, the elastic conductive member 24 of the flexible circuit board 20 can also provide support through the boss 16 of the stamping housing 10, and adjust the protrusion height H through the through-port 33 of the insulating member 30, thereby increasing the reliability of the assembly structure. Of course, the present case is not limited to this.

[0081] In addition, in this embodiment, the housing 10 and the insulating member 30 are both two-piece disassembled and assembled structures. Figure 7 As shown, after the housing 10, the flexible circuit board 20, the insulating member 30 and the circuit board assembly 4 are assembled (see Figure 5 ), the other upper cover assembly 50 or the input socket 51 can be connected to complete the assembly. Of course, in other embodiments, each split component (such as Figure 2A and Figure 2B The assembly sequence can be adjusted according to actual application requirements, which is not a necessary feature of the present invention and will not be described in detail here.

[0082] Fig. 8A , Figure 8B , Figures 9 to 11 , Fig. 12A and Fig. 12B The second embodiment of the present invention discloses a power supply assembly structure. In this embodiment, the power supply assembly structure 1a and Figures 1 to 7The power supply assembly structure 1 shown is similar, and the same component numbers represent the same components, structures and functions, which will not be repeated here. In this embodiment, the positioning seat 14a of the shell 10 further includes a reinforcing plate 17, which is connected between the flexible circuit board 20 and the bearing surface 13 of the shell 10, and is assembled with an elastic conductive member 24 that supports the flexible circuit board 20. In this embodiment, the positioning seat 14a includes at least one positioning column 15, and the flexible circuit board 20 includes at least one first positioning hole 25, which is spatially opposite to the at least one positioning column 15. The reinforcing plate 17 includes at least one second positioning hole 171 which is spatially opposite to the at least one positioning column 15. When the flexible circuit board 20 (including the reinforcing plate 17) is assembled with the shell 10 (such as Fig. 9 ), at least one positioning post 15 passes through at least one second positioning hole 171 and at least one first positioning hole 25 in sequence, so that the flexible circuit board 20 is assembled to the bearing surface 13 of the housing 10 along the second direction (opposite to the Z-axis direction), and the elastic conductive member 24 is located on the reinforcing plate 17 of the positioning seat 14a. In addition, the insulating member 30 also includes at least one auxiliary positioning hole 34, which is spatially opposite to the at least one positioning post 15 and is adjacent to the through hole 33. When the insulating member 30 is assembled to the flexible circuit board 20 and the housing 10 (such as Fig.10 ), at least one positioning post 15 also passes through at least one auxiliary positioning hole 34, so as to facilitate the alignment of the through opening 33 of the insulating member 30 and the elastic conductive member 24 of the flexible circuit board 20. In other words, when the flexible circuit board 20 or the insulating member 30 is fixed to the bearing surface 13 of the housing 10, the assembly process can be simplified by the design of the positioning seat 14, the positioning post 15, the second positioning hole 171, the first positioning hole 25 and the auxiliary positioning hole 34. Of course, the present invention is not limited to this.

[0083] In this embodiment, after the housing 10, the flexible circuit board 20 and the insulating member 30 are assembled, the elastic conductive member 24 of the flexible circuit board 20 and the top surface of the insulating member 30 form a protrusion height H (eg Fig. 12A In addition, after the main circuit board 40 is further assembled onto the insulating member 30, a mounting gap G is formed between the conductive pad 43 of the main circuit board 40 and the top surface of the insulating member 30 (as shown in FIG. Fig. 12BAs shown). Since the installation gap G is smaller than the protrusion height H, when the main circuit board 40 of the circuit board assembly 4 is assembled onto the insulating member 30 and the housing 10, the conductive pad 43 on the bottom surface of the main circuit board 40 can be close to the through-port 33 and pressed against the elastic conductive member 24 to form an electrical connection, thereby simplifying the assembly process and allowing the assembly of the main circuit board 40 to be completed through automated assembly. Of course, the type of conductive pad 43 pressed against the elastic conductive member 24 in this case can be adjusted according to actual application requirements. On the other hand, the elastic conductive member 24 of the flexible circuit board 20 can also provide support by adding a reinforcing plate 17 and adjusting the protrusion height H through the through-port 33 of the insulating member 30, thereby increasing the reliability of the assembly structure. Of course, the method of changing the protrusion height H in this case is not limited to the illustrated embodiment and will not be repeated.

[0084] In summary, the present invention provides a power supply assembly structure, which realizes the electrical connection of the LED indicator light and the fan through a flexible circuit board, so as to simplify the assembly structure, improve the space utilization, and realize the automatic assembly of the main circuit board. The flexible circuit board for realizing the power connection of the LED indicator light and the fan is arranged below the main circuit board, and does not occupy the parts space on the main circuit board. In addition, due to the thin thickness of the flexible circuit board, it does not occupy the parts space below the main circuit board. When the flexible circuit board is fixed to the bearing surface of the shell, the assembly process can be simplified by the design of the positioning seat, positioning column and positioning hole. On the other hand, the elastic conductive part of the flexible circuit board can provide support by stamping the boss of the shell or adding a reinforcing plate, and adjust the protrusion height through the opening of the insulating part, thereby increasing the reliability of the assembly structure. When the LED indicator light and the fan are designed on the rear end side of the shell, their power supply needs can be realized through the flexible circuit board, and are clamped by the assembly of the shell and the insulating part. The elastic conductive part of the flexible circuit board can be exposed through the opening of the insulating part to a protruding height. When the main circuit board of the circuit board assembly is assembled to the gap between the insulating part and the shell is smaller than the protruding height, the conductive pad on the bottom of the main circuit board can be close to the opening and pressed against the elastic conductive part to form an electrical connection, thereby simplifying the assembly process and allowing the assembly of the main circuit board to be completed through automated assembly. On the other hand, when the circuit board assembly is installed on the shell and the insulating part, the input socket, primary circuit, secondary circuit and output gold finger on the circuit board assembly are arranged from the rear end side of the shell to the front end side of the shell. The power supply required by the electrical device on the rear end side can be connected through the flexible circuit board between the insulating part and the shell, and then electrically connected to the synchronous rectifier (SR) circuit board on the secondary circuit through the conductive pad on the bottom of the main circuit board. The flexible circuit board is sandwiched between the shell and the insulating part, and a sufficient distance can be maintained between the primary circuit and the secondary circuit. In other words, the design in which the LED indicator light and the fan on the rear end side of the shell are electrically connected to the conductive pads below the main circuit board through the flexible circuit board helps to simplify the assembly structure of the shell, flexible circuit board, insulating member and circuit board assembly. The flexible circuit board can be pre-fixed to the shell, eliminating the use of flying wires and being free from wire restrictions, thereby improving space utilization and facilitating the automatic assembly of the main circuit board.
